Hey there! I'm a supplier of BOPP tape jumbo rolls, and today I wanna chat about the heat resistance of these awesome products.
First off, let's get into what BOPP tape is. BOPP stands for Biaxially Oriented Polypropylene. It's a type of plastic film that's widely used in the packaging industry. BOPP tape jumbo rolls are these huge rolls of tape that are used in large - scale packaging operations. They're super popular because they're cost - effective, strong, and come in various types.
Now, heat resistance is a big deal when it comes to BOPP tape. You see, in different environments, the tape might be exposed to high temperatures. For example, if the packages are stored in a warehouse where the temperature can get pretty high during summer, or if they're transported in trucks that can heat up under the sun. If the tape doesn't have good heat resistance, it can start to lose its adhesion or even melt, which is a total disaster for the packaging.
The heat resistance of BOPP tape jumbo rolls mainly depends on two things: the base film and the adhesive.
Base Film
The BOPP base film itself has a certain heat - resistant property. BOPP is a thermoplastic polymer, which means it can become soft and deform at high temperatures. Typically, the melting point of standard BOPP film is around 160°C - 170°C. However, in practical applications, the tape doesn't need to withstand such high temperatures before it starts to have problems.
Most of the time, we start to see issues when the temperature approaches 80°C - 90°C. At these temperatures, the BOPP film might start to expand slightly, which can cause the tape to wrinkle or lift at the edges. This is bad news because it can compromise the integrity of the package.
But don't worry, we can improve the heat resistance of the base film. Some manufacturers add special additives during the production process. These additives can increase the film's heat - deflection temperature. So, instead of starting to have problems at 80°C, the tape can now withstand temperatures up to 100°C or even a bit higher.
Adhesive
The adhesive is another crucial factor. There are different types of adhesives used in BOPP tape, such as hot - melt adhesives and acrylic adhesives.
Hot - melt adhesives are commonly used because they're fast - drying and cost - effective. However, their heat resistance is relatively limited. In general, hot - melt adhesives start to lose their adhesion strength when the temperature goes above 60°C - 70°C. At these temperatures, the adhesive becomes softer and can't hold the tape firmly to the surface.
On the other hand, acrylic adhesives have better heat resistance. Acrylic adhesives can usually withstand temperatures up to 90°C - 100°C without significant loss of adhesion. This makes them a great choice for applications where the tape might be exposed to higher temperatures.
Our Product Range
As a BOPP tape jumbo roll supplier, I offer a wide range of products with different heat - resistant properties.
-
Common BOPP OPP Packing Tape Jumbo Roll: This is our standard product. It uses a regular BOPP film and a hot - melt adhesive. It's suitable for normal packaging applications where the temperature doesn't get too high. It's cost - effective and works great for most everyday packaging needs.
-
Customized BOPP OPP Packing Tape Jumbo Roll: If you have specific heat - resistance requirements, we can customize the tape for you. We can use special additives in the base film and choose a more heat - resistant adhesive to meet your needs. Whether you need the tape to withstand 80°C, 90°C, or even higher temperatures, we can make it happen.
-
Super Clear BOPP Adhesive Packing Tape Jumbo Roll: This tape is known for its excellent clarity. It also has good heat - resistant properties. It uses an acrylic adhesive, which gives it better performance in high - temperature environments compared to tapes with hot - melt adhesives.
Testing Heat Resistance
We take the heat resistance of our BOPP tape jumbo rolls very seriously. That's why we conduct various tests to ensure the quality of our products.
One common test is the oven test. We cut samples of the tape and stick them to a test panel. Then we put the panel in an oven and gradually increase the temperature. We observe the tape at different temperature intervals to see when it starts to show signs of damage, such as loss of adhesion, wrinkling, or melting.
Another test is the real - world simulation test. We send our tapes to different regions with different climates. We use the tapes to package products and then monitor how they perform over time. This helps us understand how the tape will behave in actual use cases.
Choosing the Right Tape for Your Needs
When you're choosing a BOPP tape jumbo roll, you need to consider the heat - resistant requirements of your application.
If you're packaging products that will be stored in a normal indoor environment, our common BOPP OPP packing tape jumbo roll should be more than enough. It's reliable and affordable.
However, if your products will be exposed to higher temperatures, like during long - distance transportation in hot weather or storage in a hot warehouse, you might want to go for our customized tape or the super clear BOPP adhesive packing tape. These tapes are designed to perform better in high - temperature conditions.
